| Research Abstract |
Extrapolation plays an essential role for evaluating sea extremes frequencies, which is why the concept of return period has been in troduced. But we use the return period(or the extrapolation) with out being aware of the hidden double meanings. The return period employed in handling the past record is substituted for the period of the coming successive event in the future. We can obtain the design for ce(the return level) by extrapolation of the observed data in the past years, while we should apply it for the future by the extension over the real time, which is ano ther extrapolation. We should notice the limitations for extending the return level's estimation, by in troducing the important in dices : the degree of experience and the durability.
